Addresses of Bitmap Files

How Bitmap Files Are Created for Pictures

There are two kinds of pictures: those created for letters, and those requested directly or indirectly for figures in the
source files. The tex4ht.c utility extracts the figures from the foo.dvi file into a foo.idv file, and places in foo.lg
messages of how to extract the figures. The t4ht.c utility, uses the requests listed at foo.lg, to activate the G-script
from tex4ht.env for the different figures. However, if a F-script is available, it is used instead for the
letters.

References to Bitmap Files of General Pictures

The command

\Configure{IMG}{<img\Hnewline src="foo.dir/}{" alt="}{" }{ />}

in the configuration file adds the prefix

foo.dir/

to the file names.

The default setting uses the configuration

\Configure{IMG}{<img\Hnewline src="}{" alt="}{" }{ />}

Placement of Bitmap Filess of General Pictures

Add to the ‘G’ script in tex4ht.env a command to move the bitmap files to the desired destination (e.g., ‘Gmv %%3foo.dir/.’).

Avoiding bitmaps within formulas

Q. I found that some equations have smaller fonts than the others. I wonder why the size of the equations changesalong the document.

Some equations and symbols are converted to bitmaps–I guess they are the parts you are concerned
about.

If you try the command ‘ mzlatex filename’, provided you have the xhlatex-like script of mzlatex configured,
you’ll get the bitmaps removed in favor of unicode symbols and mathml formulas. In such a case, one will need a
mathml-enabled browser to view the outcome.

If you don’t care using the MS SYMBOL font, which non-pc browsers are likely not to recognize, try
the command ‘ htlatex filename "" "symbol/!" ’. It will resolve the bitmap problem for of the
characters.

Setting bitmaps within formulas

A code similar to the following one may be used to configure instructions like ‘\int_{xxx}^{yyy}’ and
‘\sum_{xxx}^{yyy}’ to produce pictorial representations within non-pictorial formulas.

\includegraphics

Conditional bitmap conversion for imported graphic files

Q. How to avoid the conversion of eps files to PNG’s, included through the \includegraphics{...} command’,each time the source file is run across tex4ht.

Compile your source with the command line ‘ htlatex filename "html,info" ’, and check the log file for the
information provided there. In particular, the ‘\Configure{graphics*} {wmf} ...’ example may be adapted for
dealing with eps files, where a conditional conversion is requested within the ‘\Needs{"..."}’ command (possibly
indirectly through a call to a script for doing he job).

Clickable Thumbnail Images

Q. How an image can be made a thumbnail to be clicked on for bringing up the full size image.

Other

Missing Configurations

Q. I am attempting to convert a Ph.D. thesis written in LaTeX, using a locally developed class ths.cls based on thereport class, which redefines some elements of the class for local needs. The output is lacking the Tableof Contents and the Lists of Figures and Tables, and the bibliography at the end is only minimallyformatted.

The problems result from a lack of a configuration file for the thesis class. Try introducing a configuration file
similar to the following one.
